The Guild concept feels much like a mix of actors and messaging from Erlang and Go. Not as restrictive as Erlang, but not as permissive as Go. (there was a nod to Elixir/Erlang in the slides)
Actually, I think Go is some kind of multi-thraeding (goroutine is only a useful mechanism on the "threads" and can't help to avoid multi-threads difficulties (but this design helps to reduce difficulties)).
I would like to thank the team behind this proposal, very much, by the way. I have not tinkered with Ruby in a few years, but this looks like a major breakthrough.
